Research Interests

Global Hydrodynamic Modeling

My major research topic is hydrodynamic modeling of surface waters at the global scale. The physics of surface water flow is relatively simple, but considerable efforts are required to represent complex river and floodplain topography which governs the surface water flow. My approach is the full-use of high-resolution satellite-based hydrographical datasets, which are available at the global scale. The goal of my study is to realistically simulate/predict the surface water hydrodynamics (river discharge, water level, flooded area) by proper approximation of the river and floodplain topography.

-- CaMa-Flood: Global River-Floodplain Model

-- FLOW: River Network and Topography Upscaling

Remote sensing of surface waters

In addition to the global hydrodynamic modeling work, the global-scale observation of surface waters is essential to understand the global hydrodynamics. I'm using some satellite products (DEM, water mask, inland water altimetry) for the validation, calibration, and the development of the global hydrodynamic model.

--MERIT DEM: A high-accuracy global DEM

--MERIT Hydro: Global hydrography datasets

--G3WBM: Global 3sec (90m) Water Body Map

--GWD-LR: Global Width Database for Large Rivers

--SWOT: Surface Water and Ocean Topography mission.
